  • DRIVE MOTOR DISPLACEMENT CONTROL
    Publication number: 20240110365
    Abstract: A power machine can include a control device and a hydraulic circuit that can include a hydraulic pump in communication with a hydraulic motor that is configured to operate with infinitely variable displacement. The control device can be configured to determine a control value based on a commanded travel speed for the power machine and a pressure in the hydraulic circuit, and control a run-time displacement of the hydraulic motor based upon the determined control value.

  • Drive motor displacement control
    Patent number: 11866912
    Abstract: A power machine can include a hydraulic drive system that includes an infinitely variable hydraulic drive motor. A run-time displacement of the hydraulic motor can be adjusted based on commanded travel speed or based on a output torque. In some case, the run-time displacement can be selected from one of a plurality of displacement ranges, such as a high range and a low range.

  • SYSTEMS AND METHODS FOR CONTROLLING SKID-STEER POWER MACHINES
    Publication number: 20230193593
    Abstract: A power machine can include a control device configured to select a ground-engagement mode from a plurality of ground-engagement modes. An operator input can be received from an operator input device to command movement of one or more drive actuators to provide turning travel. The one or more drive actuators can be commanded to provide modified turning travel based on the selected ground-engagement mode.

  • SYSTEMS AND METHODS FOR CONTROLLING ENGINE SPEED
    Publication number: 20220340016
    Abstract: A power machine can include an engine control module configured to determine a target operational speed of the power machine and control the engine based on the target operational speed. A drive controller can be configured to control operation of a hydraulic drive pump or other work element to decrease engine speed toward a target stabilization speed that is lower than the target operational speed.

  • SYSTEMS AND METHODS FOR TRACTION LOCK ENGAGEMENT CONTROL FOR A POWER MACHINE
    Publication number: 20210339730
    Abstract: A power machine can include a traction lock system to stop movement of the power machine. The traction lock system can include a controller configured to receive a brake input from an operator. In response to receiving the brake input, the controller can temporarily command a target (e.g., reduced) speed of the engine before engaging the brake.
